    摘要: A method of electrophotographic printing is disclosed. A recording medium comprising a photoconductive member and photo-modulation member laminated to each other, both exhibiting a photoelectric effect and a sensitized member made of a chargeable photoconductive member are arranged so as to face each other. A first electro-magnetic radiation beam (abbreviated in a beam hereinafter) which is intensity-modulated with data to be recorded is radiated to the recording medium at the photoconductive member side thereof to record the data to the photo-modulation member with the photoelectric effect. A second beam of constant intensity is radiated to the recording medium to emit therefrom a third beam exhibiting intensity variation subjected to the recorded data. The sensitized member is exposed with the third beam to form thereon a charge image corresponding to the recorded data. Toner is stacked onto the sensitized member formed with the charge image to form thereon a toner image. The toner image is then transferred onto a printing paper, thus to perform repeated printing utilizing the data once recorded to the recording medium.

    摘要: An information recording medium includes a first transparent electrode, and a carrier transport layer formed on the first transparent electrode for generating an electric current on the basis of fed carriers. A carrier generation layer formed on the carrier transport layer serves to generate carriers corresponding to a distribution of an intensity of incident information-writing light containing information, and serves to feed the generated carriers to the carrier transport layer. An electric power supply electrically connected to the first transparent electrode serves to generate an electric field corresponding to the distribution of the intensity of the incident information-writing light in cooperation with the carrier transport layer and the carrier generation layer. A photo-modulation layer formed on the carrier generation layer serves to record the information in the incident information-writing light in response to an application of the electric field generated by the electric power supply, and serves to modulate applied information-reading light in accordance with the recorded information. The photo-modulation layer is made of a complex member of high-molecule material and liquid crystal. A second transparent electrode is formed on the photo-modulation layer, and is electrically connected to the electric power supply. The carrier generation layer is made of inorganic material. The carrier generation layer may be made of organic material. In this case, a separating layer is provided between the photo-modulation layer and the carrier generation layer.
